County Migration Flows
Methodology
The following data come from the U.S. Census Bureau’s County-to-County Migration Flows dataset. Figure @fig-results shows net migration for Kansas counties. Table @tbl-results shows inflow, outflow, and net flow by county. Net flow (i.e., migration) is given by the following simple calculation:
\[ \text{Net Flow}_i = \text{Inflow}_i - \text{Outflow}_i, \]
where \(\text{Net Flow}_i < 0\) indicates the number of indiviuals leaving county 𝑖 exceeded the number of individuals entering county 𝑖 during the sampling period.
